Database:Migrations
From OpenSimulator
This table is of little use to the enduser in any direct fashion, except perhaps to verify the database schema version. It is used by the software to automatically detect the necesity to migrate the database.
The two columns in the table are 'name' and 'version'. 'version' is pretty self-documenting; name a little less so. 'version' is the column of typical interest, though 'name' is likely informative too.
